Abstract While immunity is frequently suppressed when birds engage in strenuous migratory flights, whether and how changes during the rapid accumulation of energy stores preparation for migration remains largely unknown. Here, we induced pre-migratory fattening through controlled daylight common quails Coturnix coturnix regularly assessed a marker constitutive innate (Leukocyte Coping Capacity or LCC) measures body composition (lean fat mass). LCC responses were highest mid-fattening phase lowest was completed. At mid-fattening, also found that kept higher proportion lean mass (i.e. accumulated less fat) had peaks. Our results indicate undergo immunological as they accumulate propose this could be due to competing trade-off processes between metabolic remodelling immune system function. Summary statement Immunity vital migrating new environments. It costly competivite other physiological processes. Here bring evidence on process birds.
